The drums 1 1, upon which the cylindrical veneer-boxes are formed, are mounted to slide longitudinally in the upright portions 1' of the frame and are given reciprocating movements by the following mechanism: The drum-shafts 5 5' are fixed to the axis of said drums and are moved by slidable bearings 2 2, the bases 2 of said slides moving in ways in the stationary frame. Pivotally connected to the slidable bearings 2 2 are rocker-arms 3 3, to which are connected rods 4 4, which in turn are connected, by means of wrist-pins, to spur-wheels 6 6, said Wheels being in the nature of cranks from which the rocker-arms 3 3 are oscillated. The spur-wheels-6 6 are rotated to impart such movements from a pinion 7 on a shaft 8, the latter lying at right angles to the plane of the machine and provided with bearings in the frame, as shown in Fig. 3. The shaft 8 is driven through a miter-gear 9 thereon, which is engaged by a smaller miter-gear 10 on a shaft 11,the latter being the main power-shaft, which is driven by a pulley 11', said pulley being belted to the driving power-shaft. (Not shown.) The power transmitted from shaft 11 to shaft 8 is controlled by a clutch 17 on shaft 8, (see Fig. 3,) which is movable in and out of engagement with the miter-gear 9 by hand operating-lever 12, fulcrumed on a shaft 13 and connected with said clutch 17 by shifting lever 16, crank 15, and arm 14, the latter being an extension of the hand-lever 12.

The rotary movements are imparted to the drums 1 1 through the following mechanisms: The outer ends of said drums have fixed thereto spur-wheels 40, which gearwith pinions 39 on shaft 38. These pinions 39 are splined upon shaft 38 and are therefore rotated by said shaft and are permitted to have sliding movements along said shaft when the slidable bearings 2 2 are given the horizontal reciprocating movements, hereinbefore referred to. From Fig. 1 it will be observed that the pinions 39 have their boxes connected with the upper ends of the bearings 2 2. The shaft 38 is] given intermittent rotary movement from the main power-shaft 11 through a crank-disk 21, to which the lower end of connecting-rod 31 is pivoted. The shaft 20, to which the disk 21 is fixed, is driven from the main powershaft 11 through spur-wheels 18 and 19, the

latter wheel being controlled by a clutch 22 i on shaft 20, wheel 19 being also on the same shaft. The clutch 22 is operated to be thrown in and out of gear by a hand-lever 27, which is connected to a shifting lever 27 on shaft 26 and is attached to said clutch by links 28 and 29. (See Fig. l.) The connecting-rod 31 is attached at its upper end to the rock-shaft 33 by a crank-arm 32. Power is transmitted from shaft 33 toshaft 38 through connectingrod 35. The upper end of this rod 35 is attached to shaft 33 by an arm 34 and adjustable yoke 35', which is pivoted to the connecting-rod 35 and is moved to the proper posi- 49 and 49.

tion on the arm 34 and is then secured by a set-screw. (See Fig. 3.) The lower end of connecting-rod 35 is connected to housing 36, which carries a pawl 36'. Said pawl rides over a ratchet 37 on the downward stroke of the connecting-rod 35 and engages said ratchet on the upward stroke to rotate shaft 38.

42 1 designates adjustable connecting rods, which are pivoted to arms 41, fast upon the rock-shaft 33. The lower ends of said rods 42 have fixed connections with a vertically-slidable support 43, in which the nailing-drivers 44 are held. The nails 52 are placed in a hopper 71, which is hinged at its front to a support 72 and the bottom of which is provided witha number of parallel slots, through which the nails project and are suspended by their heads, as shown in Fig. 3. The nail-hopper is supported in an inclined position and is vibrated to cause the nails to travel therein by means of a lever 73, hinged at 74 to a crosssupport 64, and has a pivotal connection with a lever 75, which in turn is pivoted at 76 to the slidable support 43. Extending forwardly from the hopper are a series of nail-chutes 65, which are connected at their forward ends to the cross-support 64. (See Figs. 4 and The chutes 65 have slots or nail-passages 65 extending throughout their lengths and through which the nails travel downwardly, being suspended therein by their heads. (See Fig. 8.) Below the forward ends of these chutes and attached to the support 64 are a series of casings 67, which support the nailseparators. (Shown in Fig. 7.) Each of these separators has a journal portion 63, which passes through openings in the support 64 at the rear of said casings, so that the heads 63 of said separators lie within the casings 67 at the exit ends of the chutes 65. The heads 63", which are inclosed at the front by lips parted to said separators by means of a longitudinal reciprocating rod 59, which is connected at suitable points to said separators by cranks 62, which are fixed to the journals 63 of the separators and have pivotal connections with sleeves 60 on said rod 59. The sleeves 60 are held firmly at one end by collars, and at the other end they are yieldingly held by springs 61. (See Fig. 7.) Reciprocating movement is imparted to the rod 59 from the slidable support 43, as follows, (see Fig. 7:) On said support there are two antifrictionrollers 53, which inclose a cam-bar 54, pivoted at its upper end to a rigid arm 54, which is attached to the support 64 at one end and to the upright frame at the other end. The lower portion of the cam-bar 54 has a suitable bend to impart the necessary movement to a lever 56. The lower end of the cam-bar is connected to the lever 56 by a pivotal link 55, said lever 56 being fulcrumed at 57 and having its upper end pivoted at 57 to link-lever Oscillating movements are im-' 58, which in turn is pivoted to one of the sleeves 60 on rod 59. It will thus be seen that in the vertical movements of the slidable support 43 longitudinal movement will be imparted to the rod 59 to move it in one direction and also in the reversed direction, during which the nail-separators, Fig. 7, are given an oscillating movement. the rod 59 is movedto'the left, as shown in Figs. 1 and 7, the lips 49 of said separators move to the position shown in Fig. 4 and exclude the passage to all but one nail 52, which is shown to lie on the inner side of the lip 49 and to permit said nail to pass into the opening 63". When the nails are thus permitted to pass one at a time from the guides 65 into the separators, they drop into the nail-tubes v 69, which communicate with an inclined passage 70, that in turn communicates with opening46 in the nail-magazine, said magazine consisting of two parts 45 45, which are united. Within the nail-magazine there are pivotallymounted jaws 47 at 48 and 48, the lower ends 50 of said jaws having openings 50, which form the lower terminal of the opening 46 and which hold the nails in a suspended position for the nail-driver 44 to engage the heads thereof, as shown in Fig. 8. As the nail-driver 44 descends these jaws are spread apart against the pressure of a coilspring 51, that normally maintains them closed, and are thus opened when spread apart to permit a free exit of a nail 52 under the end of the driver, at which time said nail is driven through the veneer into the bottom of the box. inder of veneer has been formed and united at the bottoms and tops and at the center of each box the rotary movement of the drums is changed from an intermittent movement to a continuous rotary movement, during which the cylinder is sawed through at both ends and at the center to construct two boxes from each cylinder thus formed. This continuous rotary movement is transmitted by the following mechanism: 93 designates a shaft which is driven from the main power-shaft 11 through gears 18, 19, and 19, the latter gear being loose on said shaft and controlled by a clutch 30, that is operated from a lever 23, connected to a shifting lever 26 on shaft 26 by link connections 24 and 25. The shaft 93 carries a pinion 93, which gears with the spur-wheel 40 on one end of the drums 1. When the shaft 93 is thrown in gear with the power-shaft 11, it will be understood that the shaft 33 .is idle, having performed its operation. Shaft 38 is driven from the drum-gear 40. The gear 39 on the opposite end of said shaft 38 drives the other drum 1 at the same rate of speed as the adjacent drum is driven, and a similar continuous movement is thus imparted to both drums. Before power is put into the shaft 93 the saw-frame 86, which swings on shaft 87, is moved into an operative position to bring the saws in contact For example, when After the cylwith the box-cylinder by means of a hand-lever 91, which is fulcrumed upon shaft 13 and is connected to the saw-frame 86 by a lever shaft 11 by pulleys, one of which, 87, is shown in Figs. 2 and 4:.

'90 designates the two end saws and three center saws mounted upon a mandrel 89 in swinging frame 86. The mandrel 89 is driven from shaft 87 by a belt 88, passing around pulleys on said shaft and mandrel. The two end saws are adjustable to proper positions to cut the ends of the boxes, and the central saws separate the disks which form the lids of the boxes. One complete revolution of the drums is required to cut the boxes to their respective sizes, after which the power is shut off and the drums are withdrawn horizontally in opposite directions from the cylinder by throwing into gear the clutch 17.

77 designates an independent central drum which is removed with the boxes, after which said boxes are detached from said drum, and the disk portions forming the tops 95 are then detached from said central drum. This central drum is the subject-matter of the pending application hereinbefore referred to and from which the present application is divided. This central drum and the two end drums 1 1 are inclosed by a hood consisting of three partsto wit, a rearward stationary part 78, a bottom part 78, hinged to said rearward part, and a forward part 78", hinged to the front edge of\the bottom part 78'. These hinged portions 7 8 and 7 8" are operated upon their hinges to open and close by means of a lever 82, fulcrumed at 83 to a stationary part of the frame and which is coupled to a lever 80. The lever 80 is fulcrumed at 81 to the frame, and upon this lever 80 the hinged portions 78 and 78 of the hood are supported and held. This hood is also subject-matter of the pending application hereinbefore referred to and requires no further illustration or description herein.

Having described various essential features of the invention, I will now describe briefly the operation thereof. The sheets of veneer are cut to the proper sizes and are laid upon the feed-table 94 properly assembled and united with the parts that form the bands. (For a detailed description of the assembling of the veneer sheets and the bands see my Patent No. 7063M, dated August 5, 1902.) The veneers are moved into a point where they are caught by the lip 95, (see Fig. 3,) which is on the central drum 77. When in this position, the nail devices unite the veneer to the disk portions 95 and 95", forming the tops and bottoms of the boxes. The drums being rotated intermittently, as hereinbefore described, the veneer is nailed around said tops and bottoms until one complete revolution of the drums is made. The nailing mechanism'is then stopped by throwing out of gear the shaft 20 by lever 27. The shaft 93 is then thrown in gear by its respective lever 23. The saws having been moved into operative position with relation to the drums by lever 91, said drums are given one complete and continuous rotation from shaft 93, during which the cylinder formed upon the two drums is cut to the respective sizes to complete two boxes. The power is then cut off from shaft 93'and the inclosing hood is lowered, after which the drums are moved outwardly by lever 12, throwing in operation clutch 17, and the boxes are removed from the hood.

Having described my invention, I claim In a cylindrical-box machine, the combination with nail-chutes, or rotary nail-separators to receive the nails one by one from said chutes, said separators having journal extensions which are mounted in suitable bearings, crank-arms connected to said journals and by means of which rotary movements are imparted to the separators, a horizontal rod mounted parallel with the journal-bearings, a series of spring-controlled sleeves mounted upon said rod and having connection with the crank-arms, and a system of lever connections for operating said sleeves to impart oscillating movements to the crank-arms, substantially as set forth.

In testimony whereof Iaflix my signature in presence of two witnesses.
